If Metal Gear Solid 4 truly is the last game in the series (please please no), it's going to have gotten quite a send-off: a limited-edition gunmetal PS3 in Japan, a new $499 PS3 bundle in the rest of the world, the North American launch of the DualShock 3, and, uh, some wireless headphones. Well, not just any wireless headphones: a limited-edition run of Sony's hot 7.1-channel MDR-DS7000s, with different artwork on each can. Sadly, it doesn't look like these are going to be all that easy to get -- only 30 will be randomly handed out to those buying MGS4 bundles from the Japanese Konami store from now until June 1. Better get clicking, Sparky.
